Who, me? If Cthulhu had deigned to make an appearance a few months sooner, it looks like my conjecture would have lasted a lot longer. It's all because I kept forgetting to feed the shoggoth, no doubt.
The trigger sequence only needs two small active regions -- a Herschel plus a pre-honeyfarm or pre-traffic light -- but I guess I can see why it hasn't happened to turn up before now:
x = 29, y = 60, rule = B3/S23
In general, it fits right in with my revised conjecture that new bit counts will appear whenever they darn well feel like it.
Also the likelihood that a new highest bit count will be odd rather than even seems to be heading gradually toward 50% (because as the bit-count goes up, the probability gradually decreases that a Big Enough(TM) empty space will be available for a Big Enough symmetric still life to stabilize, before something asymmetrical touches it and modifies it.)
